1. A domestic duck that is a hybrid of the Pekin duck and Muscovy duck.
   • 2016, Michaela DeSoucey, Contested Tastes: Foie Gras and the Politics of Food, page 49:

     Only male mulards are used in foie gras production; the females' livers are considered “too veiny.”

From mulet (“mule”), because it too is a hybrid of two species.
